I did some digging, it seems you can build libfontconfig either with
libexpat or with libxml2, at your will.
My distribution (OpenSuse) decided to build libfontconfig with
"configure --enable-libxml2=no", so that libexpat is used.
No idea why they did like this.
 
What is your "gdlib-config --libs" output? Does it mention "-lxml2"?
So then only the libexpat case would be broken.

For the pthreads thing, perhaps this is dependent on the glibc 
and/or gcc used, in my case it is glibc 2.10.1 and gcc 4.4.1.
